My PSA Ar9 doesn’t get any primer strikes (ammo is fine on other guns). I verified bcg/firing pin are working correctly. FCG is ALG ACT fwiw.
Must be a headspace issue? The barrel is a Foxtrot Mike replacement. Any tips of what went wrong? Clearly I am not a gunsmith this barrel was put on long ago but is unfired I’m guessing. My son is getting frustrated it doesn’t work.
